ALEXANDER MILLER, OF NEW YORK, N. Y.

ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 412,775, dated October 15, 1889.

Application filed July 23, 1888.

To all whom it may concern.-

Be it known that I, ALEXANDER MILLER, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Elevator-Buckets, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to buckets used more especiallyfor the handling of materials of an adhesive or packing nature, and which the ordinary buckets do not readily discharge, especially if the elevator of which they form a part runs at a slow speed.

I will now proceed to describe my invention in detail, having reference to the several views shown in the accompanying drawings, in which like parts in the various figures are indicated by the same letter.

Figure 1 is an end elevation of the bucket, shown in section, the section being taken at the line A B. Fig. 2 is a side elevation, also shown in section, the section being taken at the center line; and Fig. 3 is a plan view,

.looking down on the top or open side of the bucket.

My invention comprises a frame made either of wood or metal or a combination of both. I

.C is the end piece of the bucket-frame, to which is attached the slats D and the rods E. T he word frame here used is not limitedto its usual significance-that of several pieces secured together by fasteningsbut includes such a construction as might be stamped out of one piece of metal, having numerous openings therein of various shapes and sizes, and which, it will be seen, would accomplish the mouth of the bucket. I prefer to use the rods E to which to attach the bag or sack F; but

it will be readily seen that other construc- Serial No. 280,778- (No model.)

tions may be usedsuch as slats similar to Dto which the bag or sack may be nailed or sewed, for the nature of the materials to be handled by the bucket may be such that it will be desirable to make this upper slat of somevconsiderable width and fasten the bag or sack to its lower part, thus securing a bucket of large capacity, but having a bag or sack of such a depth only as will enable the bucket to be discharged, as hereinafter described. Th'e reason I prefer the rods E to which to attach the bag or sack is because I believe the bag will last much longer than if attached in another manner, under the severe action to which it is subjected, and which I will now proceed to describe.

For the purpose of describing the action of my bucket I will suppose it is used in the ordinary and well-known elevators such as are used for elevating grains, &c. As the bucket passes down what is usually termed the back leg of the elevator it is necessarily inverted, the mouth or opening being downward. It passes into the material to be elevated, and is filled in the usual manner,

- and passes up what is usually termed the front leg of the elevator, the mouth or opening being now upward. It passes up to the head-wheel of the elevator and round the same, where it becomes inverted and the material contained in it falls out by the action of its gravity, and if this material be of an adhesive or packing nature it pulls the flexible bag or sack out of the frame, as shown by dotted line N, and of course readily drops away from it, and this, it will be seen, takes place no matter how slow the bucket may be traveling. Thus there is a complete and automatic discharge of the bucket.

WVhatI claim as my invention, and desire to secure by Letters Patent, is-

An elevator-bucket consisting of a frame having a bag or sack made of fibrous or flexible material fitted into said frame and secured to said frame, for the purpose and substantially as herein described.

ALEX. MILLER.
